It is my assumption that Hilton thinks that the satisfaction guarantee is good for midpriced properties such as Hampton Inn because people at that price point might be willing to pay slightly extra to know that they will have a good nights' sleep or its free. Hilton positions its flagship brands (Conrad and Hilton) as being above the need to worry. To me, it's like cars -- the Korean brands have a reputation for needing lots of repairs, and so the manufacturers stress how good the warranty is in their ads. Lexus doesn't because it tries to image itself as being so much better that there is no need to even worry about repairs--Lexus adds stress the luxury, which is exactly what Hilton and Conrad ads try to convey.
